When we run the cpuhotplug03 test case on the arm64 machine,
we conclude that no error occurs when the cpuhotplug03 case is executed alone,
but once the cpuset_sched_domains case is executed first,
After cpuhotplug03 is executed, the error "cpuhotplug03 1 TFAIL: No cpuhotplug_do_spin_loop processes found on" occurs.
The cpuset_sched_domains test case changes the value of cpuset.sched_load_balance in the cpuset cgroup subsystem,
but does not restore the value at the end of the test.
Modify the cpuset_funcs.sh file. The test result shows that the problem is solved successfully.

Hi,
Please ignore this patch. When I was making this patch,
I used an incorrect method to fix my formatting problem.
Now I've remade a new patch, please check out the v2 version.
Kind regards,
Wang Xin
